1300$ amd computer

You're proably not in the US, are you? If you are, you're getting screwed on the price...

Ignoring the budget, I have several changes.

First, switch the CPU to a X4 955. It's basically the same, but cheaper because it doesn't have a factory overclock.

Second, switch the board for an Gigabyte GA-770TA-UD3 (no Crossfire) or Gigabyte GA-790XTA-UD4 (with Crossfire). These are much more future proof.

Third, you're buying the wrong RAM. You need dual channel sticks (i.e. two 2 GB sticks) not triple channel. Get a good set of either 1333 mhz or 1600 mhz sticks with CAS Latency 7.

Fourth, that HDD is going to be slow. You want to get the Seagate 7200.12 500 GB or 1 TB model, not the 750 GB. Or get a Samsung Spinpoint F3 in the same two sizes (500 GB or 1 TB).

Fifth, that PSU isn't that great, but it's passable. I'd definitely consider getting an Earthwatts unit from Antec. If you're planning on Crossfire, you'll need at least a 650W unit if you don't mind using power adapters.

Yeah in Australia so we get overcharged for everything. Cheers for the suggestions, especially the ram.
